title: Bis{μ-2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}bis-({2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}copper(II)).
abstract: The title compound, [Cu2(C9H10NO2)4], is built of discrete centrosymmetric dimers. The Cu(II) atoms are each five coordinated by two deprotonated Schiff base ligands that are bonded differently to the metal atoms. Of the two phenolate O atoms, one is coordinated to one Cu(II) atom, whereas another bridges the two metal atoms. The basal plane of the square pyramid around Cu(II) atoms is formed by the imino N and phenolate O atoms of the bidentate and the monodentate/bidentate Schiff base ligands. The bridging phenolate oxygen occupies the apical position of the coordination sphere with a considerably longer Cu-O bond length. In the crystal, the dimeric mol-ecules pack relative to each other in such a way that the Cu2O2 planes of adjacent dimers are orthogonal.
